Extract black .bmp background

I've been trying to get exact sprites from /weapons folder and use them for a script I'm making, but there's 1 problem.

The weapons no longer have the pink background like they used to before and I can't extract the EXACT look of a weapon.
Are there any pink background variant of these .bmp sprites ?
Or atleast .png format of these weapons.

EDIT :
Anyway, found a way to make the black background dissapear.
Here's a link for anyone interested in these sprites.https://imgur.com/a/oNTN5
